I want to refer equations and figures from the previous chapters(showing in structure). I have to find the label from that chapter each time which is consuming more time. I want pop ups for all equations and figures in the whole document.(currently it is showing equation pop up for that chapter only)
The reason for seeing references only on a per-chapter basis is the following: you have not set a master document.
In order to do so, open the main
.tex file in Texmaker (the one with all the input/includes of all your chapters). Then select
Options / Define Current Document as "Master Document".
